NON-REFILLABLE BOTTLE.

To all whom it may concern.

Be it known that I, LOUIS SCITAFFERI, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and lmproved Non-Refillable Bottle, of which the following is a full, clear, and exact description.

My invention relates to a new and inn proved form of non-refillable bottle.

An object of my invention is to provide a bottle of the above-indicated character, which bottle cannot be refilled but will permit the ready etllnx of liquid from the same.

Another object of my invention is to provide a bottle of the above-indicated character in which it is diflicult to obtain access to the means closing the same.

A further object of my invention is to provide a bottlewhich cannot be opened by exhaust pressure.

I attain the above-outlined objects by disposing a flap valve within the neck of the bottle, which valve is held in open position by means of a flexible lift, which may be detached from the valve at will.

The flap valve is so constructed that the introduction of a substance into the bottle will normally close the valve, and access to the same is prevented by a tortuous passage leading to said valve.

With the above and other objects in view, as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures, and in which- Figure l is a vertical transverse section taken centrally through the neck and adjacent parts of the bottle; and Fig. 2 is a horizontal cross sectional view taken on the plane indicated by the line 2-2 of Fig. 1 and looking in the direction of the arrow.

Described more in detail, I have shown the body A of a bottle of any suitable con- Specification of Letters Patent.

struction and material, and integral therewith is the neck 13 also of any suitable construction. Access is obtained to the body A. through the neck B by means of a bore C, and the invention relates more particularly to this bored portion and its containing parts.

lVithin the neck B and adjacent the entrance to the bore G into the body A, the bore'is dished to form a substantially semispherical valve seat Immediately above the valve seat 3, the bore is enlarged to form a valve recess 4. U-shaped in cross section or substantially semi-spherical. The upper end of the bore C is enlarged to form a stopper-receiving pocket 5. The bottom of the sto mer-receiving pocket is connected to the apex of the valve recess 4 by means oi a tortuous passage 6, in this case shown to be substantially S-shaped. As the diameter of the recess 4 is greater than the horizontal diameter of the top of the valve seat there is formed concentric with said valve seat 3, a ring shoulder 7. Tntegral with the neck B and positioned on said shoulder. is a glass lug 8, through which is fused a pin 9. which pin is also fused in the rim 10 of a valve '11, so as to form a hinged connection between said valve and said neck. The central portion of the *alve ll is depressed to show a semispherical dished pfll'llOIl 12 adapted to conform in configuration to and it within the valve seat 3. The rim '10 of the flap valve resting on the shoulder T. closes communication through the bore (3 into the body A of the bottle. It will be seen by this construction that the valve is normally closed by its own weight. so that any attempt ,to place a substance within the bottle merely results in the valve being more .[irmly closed upon its seat. .teady access is prevented due to the tortuous passage 6. As is readily seen, it would. be impossible to place any stitl' instrument within the tortuous passage, and it would be very dilli cult with any kind of an instrinnent, to fish for the valve in order to unseat the same. This tortuous passage will further prevent any attempt to lift the valve by the force oi suction pressure, for upon the introduction of a liquid, the tortuous passage would tend to break its force and said liquid would entirely fill the bore and weight the valve.

In order to permit the initial filling of the bottle, there is extending from the rim 10 diametrically opposite the hinge connection, a stud 12 having a relatively small eye 13 therein. Vhen the bottle is manufactured, this eye is engaged by a weak hook 14: attached to the lower end of a flexible lift or wire 15, which wire is passed through the tortuous passage 6 and through the stopper pocket 5, terminating in a ring stop 16, which prevents the lift from falling into the body of the bottle. By reason of this lift being removably attached to the valve, the valve may be held in the open position shown in full lines in Fig. 1, and in this position the bottle may be filled. l Vhen in this raised position, the tension on the lift 15 maintains the valve rigidly spaced from the adjacent wall of the recess 4, preventing the valve from breaking against the wall of the bottle while the latter is being filled. After the bottle is filled, a strong pull on the lift 15 will bend the hook 14C, permitting its withdrawal from the eye 13. The valve will then fall on toits seat, as shown in dotted lines in Fig. 1 and in full lines in Fig. 2, thereby sealing the bottle against the introduction of any more fluid. The diameter of the valve is less than the shortest distance between its hinged connection and the point 18 at the entrance of the tortuous passage 6 to the recess l, so that when pouring liquid from the bottle, the valve is pocketed against the wall of the recess adjacent the hinge connection, permit-ting a clear unrestricted fiow through the bore C. After the lift has been withdrawn, the customary form of stopper 17, shown in dotted lines in Fig. 1, may be inserted in the pocket 5,

lVhile a preferred embodiment of the invention has been described, it is to be understood that many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof. It is intended that all matters contained herein in the above description or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover the full scope of the invention and is not to be given any narrower construction than the prior art demands, and that materials, sizes and relativities of parts are non-essential, except as called for in the claims.

Having thus described my invention, I

claim as new and desire to secure by Let.

in raised position, said valve having a stud projecting from the top thereof at a point farthest removed from its hinge, adapted to be engaged by said flexible lift, and constituting, when the valve is raised, the most advanced portion of said valve, said valve when so raised by tension on said lift, being pocketed adjacent to but slightly spaced from the wall of said recess, and adapted to be rigidly maintained in this position by said lift while maintaining practically an unobstructed passage for the inflowing liquid.

2. A bottle, comprising a body portion and a neck integral therewith, said neck having a bore extending therethrough, to afford an entrance to the body of the bottle, a portion of said bore, adjacent its entrance to the body of the bottle, being enlarged to form a substantially semi-spherical recess, said bore above said recess entering said recess at the apex thereof, and a flap valve hinged within and at the bottom of said recess, said valve being circular in plan and having a marginal rim with a diameter less than the shortestdistance between the hinge of the valve and the entrance of the bore to the recess, whereby when pouring liquid from the bottle, said valve is pocketed with the portion of the edge of the rim farthest removed from the hinge contacting with the side of the recess adjacent the hinge, whereby a clear, unobstructed passage is obtained through said bore.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
